The economic prospects for the preservation of perishable fresh or quick-frozen food in cold stores and transport vehicles is discussed, based on standards for allowable heat flux for the two cases (6 watts/m2 or 8 watts/m2). The importance of water vapour migration, resistance to wind and to chemical attack, notably in certain particular cases, is shown, along with ground insulation problems, especially for frozen food. For the in situ manufacture of insulating foams, the use of R11 is banned by competent international authorities despite its widely confirmed thermal efficiency, so that it will be necessary to use the new products listed in the paper. For transport, the development of group platforms and of multi-compartment vehicles seem to be the most important directions of evolution. Y.G.
